1. Examine the Thermostat
First, make sure your thermostat is telling your furnace to start.
- Replace the batteries if the monitor is empty. If the digital screen is scrambled, the thermostat could need to be changed.
- Ensure the switch is set to “heat” rather than “off” or “cool.”
- Make certain the program is set to the correct day and time and is set to “run.” If you’re having problems getting out of the schedule, set the temperature with the up/down arrows and holding the “hold” button. This will make the furnace to start if thermostat programming is causing trouble.
- Turn the temperature setting to 5 degrees above the temperature of the room.
If your heat hasn’t kicked on within a few minutes, ensure it has power by changing the fan switch from “auto” to “on.” If the fan doesn’t start, your furnace may not have power.
If you have a smart thermostat—for example one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will be determined by the model you have. Check the manufacturer’s website for help. If you still can’t get your Wi-Fi thermostat to function, contactl us at 239-214-0411 for heating and cooling service.
2. Inspect Breakers and Switches
Next, you should confirm your breaker and furnace switch are on.
- Locate your residence’s main electrical panel. If you have no idea where it is, look for a metallic metal box in your basement, garage or closet.
- Make certain that your hands and feet aren’t wet in advance of opening the panel or breakers.
- Locate the breaker marked “furnace” or “heat,” and make sure it’s switched “on.” If you discover a tripped breaker, it will be in the middle or “off” spot.
- With one hand, quickly switch the breaker to the “on” spot. If the breaker trips right away and pops back to “off,” don’t touch it and get in touch with a professional from Comfort Zone Inc at 239-214-0411 immediately.
It doesn’t matter how old your furnace is or what brand it is, it has at least one standard wall switch installed on or close to it.
- Make certain the lever is moved up in the “on” placement. If it was shut off, anticipate your furnace could take up to five minutes to ignite. (If you don’t know where to find your furnace, check your basement, garage or utility closet. It could also be in a crawl space or attic.)
3. Replace the Air Filter
When we consider heater issues, a grungy, clogged air filter is often to blame.
If your filter is too dirty:
- Your heater won’t keep heating your home, or it might get too hot from limited airflow.
- Your utility costs could be higher because your heater is operating more than it should.
- Your furnace could fail prematurely due to the fact a filthy filter triggers it to work overtime.
- Your heating may lose power if an overly filthy filter causes the breaker to trip.
Depending on what type of furnace you have, your air filter is located within the blower compartment of your heater, an attached filter case or wall-mounted return air grille.
To put in a new filter:
- Cut the power to your heating system.
- Remove the filter and tilt it toward the light. If you can’t notice light through it, use a new one.
- Insert the new filter with the arrow facing toward the heating system to keep damage from happening.
Flat filters need to be replaced monthly, while pleated filters should last somewhere in the vicinity of three months. You may also buy a washable filter that will last about 10 years. If you have children or pets, you might have to replace your filter more often.
To make changing your filter easier down the road, use a permanent marker on your heater outside or ductwork to show the airflow direction and filter size.
4. Examine the Condensate Pan
Otherwise known as drain pans, condensate pans capture liquid your furnace pulls from the air.
If moisture is leaking from your furnace or its pan has too much water in it, follow these steps.
- If your pan has a drain (look for a PVC pipe), check that it’s clear. If it should be drained, get a special pan-cleaning tablet you can buy at home improvement or hardware retailers.
- If your pan contains a pump, check the float switch. If the button can’t be moved from the “up” position with standing water in the pan, call us at 239-214-0411, because you will possibly need a new pump.
5. Check for Heating Error Codes
If failures continue, look at your heater’s plastic window to verify the blower motor’s status. Depending on the type, the light could also be mounted on the exterior of your heater.
If you notice anything other than an uninterrupted, colored light or blinking green light, contact us at 239-214-0411 for HVAC service. Your heater might be emitting an error code that requires professional help.
6. Scrub the Flame Sensor
If your heater makes an effort to start but switches off without putting out heated air, a dirty flame sensor can be to blame. When this takes place, your furnace will try to start three times before a safety mechanism shuts it down for approximately an hour.
If you feel confident with taking the panels off your furnace, brushing off your flame sensor is a job you have the ability to do yourself. Or, one of our heating service experts has the ability to finish it for you.
If you are fine with cleaning the sensor personally, you require:
- A 1/4” hex screwdriver or wrench
- Bit of light grit sandpaper, steel wool or emery cloth
- An unused paper towel
As the next step:
- Disable the heating system’s power with its wall switch or breaker. If your furnace’s gas valve isn’t electric, you have to switch off the gas along with it.
- Take off the furnace’s front panel and track the wire to the flame sensor.
- Take off the rod and use your sandpaper, steel wool or emery cloth to gently clean the metal rod.
- Clear the rod with a paper towel.
- Put the sensor back in.
- Replace the furnace doors.
- Switch the furnace’s power back on. It could proceed through a series of checks before resuming usual operation. If your heater doesn’t ignite, the sensor may require replacement or something else may be causing a problem. If this takes place, get in touch with us at 239-214-0411 for heating and cooling repair support.
7. Reignite the Pilot Light
If you own an outdated heating system, the pilot light could be extinguished. To light it, find the steps on a sticker on your furnace, or use these recommendations.
- Look for the toggle below your heating system that says “pilot,” “on” and “off.”
- Turn the switch to the “off” position.
- Don’t do anything for at least five minutes to prevent sparking a fire.
- Turn the switch to “pilot.”
- Push the “reset” switch as you move the flame of a long lighter to the pilot light opening.
- Release the “reset” switch once the pilot light is ignited.
If you have gone through the list twice and the pilot light still won’t light or remain burning, contact us at 239-214-0411 for furnace service.
Inspect Your Fuel Supply
Try turning on another gas appliance. If it doesn’t operate, your natural gas service may be turned off, or you may have run out of propane.
